LUCENE-5731: split out direct packed ints from in-ram ones
> split direct packed ints from in-ram ones
> -----------------------------------------
>
> Key: LUCENE-5731
> URL: https://issues.apache.org/jira/browse/LUCENE-5731
> Project: Lucene - Core
> Issue Type: Bug
> Reporter: Robert Muir
> Assignee: Robert Muir

>
> Currently there is an oversharing problem in packedints that imposes too many
> requirements on improving it:
> * every packed ints must be able to be loaded directly, or in ram, or
> iterated with.
> * things like filepointers are expected to be adjusted (this is especially
> stupid) in all cases
> * lots of unnecessary abstractions
> * versioning etc is complex
> None of this flexibility is needed or buys us anything, and it prevents
> performance improvements (e.g. i just want to add 3 bytes at the end of
> on-disk streams to reduce the number of bytebuffer calls and thats seriously
> impossible with the current situation).
